After the pin engages the full bore ID length, the pin vice is secured to the calibrated gauge pin/ferrule vice assembly as shown in Figure The mass is gradually released, pulling the pin through the bore This procedure is repeated using increasingly larger pins until the 100,0 g ± 5,0 g mass cannot freely pull the pin out of the bore Once this state is reached, the previous pin’s diameter is recorded as the effective diameter of the guide pin bore Repeat the above procedure for the opposite hole BS EN 61300-3-46:2011 61300-3-46 IEC:2011 –7– IEC 1208/11 Figure – Gauge pin through ferrule
